Mischa Barton is set to be reunited with her The OC co-star Willa Holland in the high school movie The Science of Cool.

The girls, who played sisters in the hit TV show, will join Steve Guttenberg, Twilight Eclipse's Kiowa Gordon and Rumer Willis when the movie begins filming this summer, Humanistic Films has announced according to Collider.com

The project has been in development for several years and Hot Tub Time Machine's William Zabka is now on board to direct.

Eden Sher, Drew Van Acker, Guy Kent and Matt Dallas are also among the confirmed cast.
